its has been done but really its not practical, go with a kw adjustable suspension and set it to soft...you will decrease handling a bit but take some harness out of the road, i also have some experience with air ride suspension, nothing is worse then blowing a line on a highway and having your frame drag on the ground....i use to be part of the mini truck scene in the late 90s early 2000s, like mentioned above lots of weight and decreased performance compared to stock.....if you have a mini show truck....added weight not a problem, handling compared to stock not a huge change, dragging frame..ouch.....the viper deserves better and trucks do too
